PCT No. PCT/DK89/00121 Sec. 371 Date Aug. 9, 1990 Sec. 102(e) Date Aug. 9, 1990 PCT Filed May 12, 1989 PCT Pub. No. WO89/10699 PCT Pub. Date Nov. 16, 1989.An apparatus for shelling shellfish such as shrimps consists of a dosing chamber (3) and a heat treatment chamber (5) separated by a slide valve (11) and sealed by cylindrical membrane valves (7, 9). From a funnel (31) the shellfish fall down into the dosing chamber (3) whose valve (7) is closed. The slide valve (11) is opened and a portion of animals fall down into the heat treatment chamber (5), whose bottom is closed by another membrane valve (9). The slide valve (11) is closed and steam at high pressure and temperature is induced into the heat treatment chamber (5). The pressure is removed from the membrane valve (9) after which the standing overpressure in the chamber (5) blows the shellfish out of the discharge opening (19) towards a rebound plate (35). Hereby the meat and shells of the shellfish are separated. |
